WebThe thermoemf of the deposited films was measured as a function of temperature in a vacuum using a home made device. It was observed that thin films of TaC and TiC yield fairly high and stable thermoemf throug hout the temperature range of stability. Under the optimized deposition conditions, thin film thermocouples were fabricated. WebIn industries, thermocouples may get subjected to varying temperatures all day long for months on end. Generally, annual calibration is advised for every thermocouple. However, for thermocouples that see constant use, calibration should be made at shorter intervals. With constant use, the efficacy of the thermocouple deteriorates over time.
